A is proportional

B and C are NOT proportional

Step-by-step explanation:

First, simplify 588 and 60:

588 divided by 6

60 divided by 6

= 98

  10

Simplify them again by dividing them both by 2

= 49

   5

Let's look at A:

441 and 45

Simplify by dividing by 9

= 49

   5

It's pretty obvious that A is proportional because the simplified values are exactly the same.

Next, let's check B:

215  and 25

Simplify by dividing by 5

= 43

   5

Now that its simplified you can compare

43   is smaller than 49

5                               5

B is not proportional

Finally, let's check C:

649 and 110

Simplify by dividing by 11

= 51

  10

Make 51 and 49 have the same denominator so we can compare them

          10         5

51 can stay the same because 5 times 2 equals 10

10

49 times 2

5 times 2

=  98

    10

Now that the denominators are the same we can compare

51 is much smaller than 98

10                                     10

Therefore, C is also not proportional.

Hope that helps :D

i got A same And B and C isnt

Step-by-step explanation:

not sure but it may be b, as i said i'm not sure.

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92
